Tektronix 2225, Operator'S Manual

Page: 62 / 79

Performance Characteristics
The electrical characteristics listed in Table 5-1 are valid for the
2225 when it has been adjusted at an ambient temperature
between + 20°C and + 30°C, has had a warm-up period of at
least
2 0
minutes, and is operating at an ambient temperature
between
0
°C and +40°C (unless otherwise noted).
Environmental characteristics are given in Table 5-2. The 2225
meets the requirements of MIL-T-28800C, paragraphs 4.5.5.1.3,
4.5.5.1.4, and 4.5.5.1.2.2 for Type III, Class 5 equipment, except
where otherwise noted.
Mechanical characteristics of the instrument are listed in
Table 5-3.

VERTICAL D EFLECTION SYSTEM
Deflection Factor
Range 5 mV per division to 5 V per division
in a 1-2-5 sequence of 9 steps.
Sensitivity increases to 500 |xV per
division with X10 vertical
magnification.
Accuracy ±3% . With X10 vertical magnifica­
tion, accuracy is ±5% .
Variable Control Range Continuously variable and uncali­
brated between step settings.
Increases deflection factor by at
